I recently realized that there are few if any city pigeons in Taiwan. I thought all cities teemed with them. But there's a reason there aren't any. Pigeon racing is a huge gambling pasttime in Taiwan.

So maybe the once-wild pigeons were captured and bred. Or maybe the pollution got them. Or maybe, the wild ones joined up with flocks of racing pigeons and disappeared from the city streets and parks forever. Or possibly, they were all killed by scooters.
